Redraw Property (ElementControl)

FarPoint.Win Assembly > FarPoint.Win Namespace > ElementControl Class : Redraw Property
Gets or sets whether the control automatically refreshes itself each time a property is set that changes the control or its value.
Public Overridable Property Redraw As Boolean
Dim instance As ElementControl
Dim value As Boolean
instance.Redraw = value
value = instance.Redraw
public virtual bool Redraw {get; set;}

Property Value

Boolean value: true to redraw; false otherwise

Setting this property to false can speed up your application during certain operations. Set this property to false when adding large amounts of data or when making many changes to a control; then when you are finished, reset this property to true. The items on the screen that have changed since this property was set to false are then refreshed.

When the control receives the focus, the control sets its Redraw property to true.

This property is available at run time only.

Note: Even if you set this property to false, some changes might be shown on the screen, depending on the type of changes and the order in which they are made.
